FIELD: radio engineering.
SUBSTANCE: in each signal processing channel on frequencies of the second and third harmonics of sounding signal of non-linear radar, echo signals are received from objects with non-linear electric properties as per the main and first side directional lobes of receiving antennae of corresponding channels, inversion of phase of signals received with side lobes with their further amplification, logic synthesis of the required reception diagram and certain antenna aperture synthesising algorithm, which ensures increase in time interval of antenna aperture synthesising, and as a result, improvement of angular resolution of non-linear radar.
EFFECT: improvement of angular resolution of non-linear radar.
